J. ULMER SINK STOPPER AND STRAINER COMBINATION Filed Feb. 2, 1959 Patented July 18, 1939 UNITED STATES PATENT OFFICE COMBINATION SINK STOPPER AND STRAINEK 1 Claim.

The device forming the subject matter of this application is a combined sink stopper and strainer. The invention aims to provide novel means for mounting the gate portion of the strainer for movement with respect to the body of the combined article, and to improve generallyand to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view,

which will appear as the description proceeds,

the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed,

may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawing:

Fig. 1 shows in top plan, a portion of a sink wherein the device forming the subject matter of this application is incorporated;

Fig. 2 is a cross section on the line 22 of Fig. 1;

Fig. 3 is a bottom plan of the combined sink stopper and strainer, the body of the article being in section.

The numeral I marks the bottom of a sink wherein is mounted a tubular outlet member 2, provided at its upper end with an outstanding flange 3 seated in a rebate I in the sink bottom I. The outlet member 2 is held in place by a nut 5 threaded on it, an annular compressible gasket Ii being interposed between the nut and the sink bottom I. In its upper surface, the outlet mem her 2 has an annular recess I.

A combined stopper and strainer 8 is provided and, preferably, is made of metal, the stopper and strainer including a tapered tubular body 9,

adapted to fit watertight but removably in the upper part of the outlet member 2. At its upper end, the body 9 is supplied with an integral closure plate I0. At its upper end, the body 9 has an outstanding flange II received in the recess "I of the outlet member 2. The closure plate II) has openings I2 arranged concentrically with respect to the center of the plate. A nut I4 is welded to the lower surface of the closure plate I0 and may be considered as part of the closure plate.

Above the closure plate II] of the body 9 is disposed a disk-like gate I5, no greater in di- 1 ameter than the flange I I of the body 9. A turning head IE, of any desired form, is welded to the gate I5, centrally thereof. The head I6 has a depending stem I'I, extended through the gate I5 and mounted to turn freely in the closure plate II] of the body 9, the stem I! being threaded into the nut I4. The gate I5 has openings I8 registering axially with the openings I2 of the closure plate ID. The openings I2 preferably are a little larger than the openings I8, to provide a ready flow for water which may run downwardly through them. The rotation of the gate I5 by means of the head I6 is limited, since the gate I5 has a depending, fixed, stop pin I9, re- F ceived in an arcuate slot 2|] in the closure plate Iii of the stopper and strainer 8.

When the openings I8 and I2 are in registration, the device functions as a strainer. By rotating the gate I5 2. little, through the instrumentality of the knob I6, the openings I8 are moved out of registration with the openings I2. During this rotation, the gate I5 is clamped down tightly on the plate ID, to prevent leakage, because the stem I1 is threaded into the nut I4. When the stop pin I9 is at one end of the slot 20, the openings IB and I2 are in registration, and the operator does not have to follow a trial and error process, to get the openings in registration. By means of the head I6, the entire device can be lifted out of the outlet member 2.

When the device is used as a stopper, rather than a strainer, the openings I2 and I8 are out of registration, and the gate I5 is clamped down tightly on the closure plate I0 of the stopper and strainer, since the stem I1 is threaded into the nut I4. The device, then, can be used like an ordinary hermetic sink plug, and no attention need be given to the fact that, by rotating the gate I5, the article can be converted into a strainer.

What is claimed is:

A combined sink stopper and strainer comprising a tubular body having a closure at its upper end, a gate above the closure, the gate 45 and the closure having openings so located as to be brought into registration when the gate is rotated, the gate having a stem threaded into the closure and clamping the gate hermetically on the closure when the openings of the gate 50 and the closure are out of registration.
